Format
Racing was held form Friday 9 April until Sunday 11 April 1999. The race was held for V8 Supercars and was Round 2 of the 1999 Shell Championship Series. The format, unique to V8 Supercar and loosely similar to the Pukekohe 500 format, consisted of two 250 km races.
The original format called for the two races to form a single race, separated by an overnight rest at half distance, however with several significant competitors retiring from the first leg a change to the regulations was announced on the Saturday evening, allowing retired cars to be repaired and restarted for Sunday's Leg 2.
